    A theoretical investigation of the possible detection of C24 in space
    Astronomical infrared spectral features at ~6.6, 9.8 and 20 micronm have recently been suggested as being due to the planar graphene form of C24 carbon cluster...
  • Publication
    A theory of gamma-ray bursts
    Recent observations and theoretical considerations have linked gamma-ray bursts with ultra-bright type Ibc supernovae (`hypernovae'). We here work out a...

    A Third Massive Star Component in the σ Orionis AB System
    We report on the detection of a third massive star component in the σ Orionis AB system, traditionally considered as a binary system. The system has been...
  • Publication
    A three-dimensional equation for the inversion of the zodiacal light brightness integral
    A three-dimensional equation for deriving the scattering properties per unit volume of interplanetary space is obtained. The equation is related to the zodiacal...
  • Publication
    A three-dimensional Galactic extinction model
    A large-scale three-dimensional model of Galactic extinction is presented based on the Galactic dust distribution model of citet{DS01}. The extinction AV to any...
  • Publication
    A Three-dimensional Study of Reconnection, Current Sheets, and Jets Resulting from Magnetic Flux Emergence in the Sun
    We present the results of a set of three-dimensional numerical simulations of magnetic flux emergence from below the photosphere and into the corona. The corona...

    A Three-dimensional View of the Remnant of Nova Persei 1901 (GK Per)
    We present a kinematical study of the optical ejecta of GK Per. It is based on proper-motion measurements of 282 knots from ~20 images spanning 25 years...
  • Publication
    A Tidal Extension in the Ursa Minor Dwarf Spheroidal Galaxy
    We report the detection of main-sequence and blue horizontal-branch stars of the Ursa Minor dwarf spheroidal galaxy beyond its tidal radius, indicating the...

    A tidal tale: detection of several stellar streams in the environment of NGC 1052
    The possible existence of two dark-matter-free galaxies (NGC 1052-DF2 and NGC 1052-DF4) in the field of the early-type galaxy NGC 1052 presents a challenge to...
